IV.Read the passage. Decide which of the following statements is True(T), Palse(F) or No information(NI)
We are all destroying the Earth. The seas and rivers are too dirty to swim in it. These is so much smoke in the air that it's unhealthy to live in many of world's cities. We've cut down so many trees that there are now areas of wasteland all over the world. Farmers in many parts of Africa can not got grow enough to eat and in some Asian countries there is too little rice. Wild animals are quickly disappearing because we have killed too many. However, it isn't enough simply to talk about the problem. We must act before it's too late to do anything about it. Join us now. Save the Earth. This is too important to ignore

Mars is the fourth planet from the Sun and is commonly referred to as the Red Planet. The rocks, soil and sky have a red or pink hue. The distinct red color was observed by stargazers throughout history. It was given its name by the Romans in honor of their god of war. Other civilizations have had similar names. The ancient Egyptians named the planet Her Descher meaning the red one.
Before space exploration, Mars was considered the best candidate for harboring extraterrestrial life. Astronomers thought they saw straight lines crisscrossing its surface. This led to the popular belief that irrigation canals on the planet had been constructed by intelligent beings. In 1938, when Orson Welles broadcasted a radio drama based on the science fiction classic War of the Worlds by H.G. Wells, enough people believed in the tale of invading Martians to cause a near panic.
Another reason for scientists to expect life on Mars had to do with the apparent seasonal color changes on the planet's surface. This phenomenon led to speculation that conditions might support a bloom of Martian vegetation during the warmer months and cause plant life to become dormant during colder periods.
